signors to Cory Corporation, Chicago, 111., a corporation of DelawareOriginal application May 21, 1956, Serial No. 356,506.

Divided and this application'March 28, 1956, Serial The presentinvention relates to a clip and cap assembly for writing instruments,such as ball point pens, mechanical pencils, fountain pens, and thelike, and more particularly to a novel spring-loadedtclip and manner ofmounting one end of the clip in the cap.

Among the objects of the present invention is to provicle a novel clipassembly for writing instruments in which the body of the clip is ofrigid construction and spring-mounted at one end in the outer end of thecap whereby the shankand exposed retaining end of the clip arespring-biased to exert a positive gripping action against the cap, butreadily yields for attaching the clip to the clothing when the writinginstrument is not in use, or for. detaching the clip and removing thewriting instrument from the pocket when intended for use.

Another and important object of the present invention is the provisionof a novel clip assembly for a writing instrument, and novel means forspring-loading the clip and tensionally retaining it in operativeposition.

The present invention further comprehends a novel ciipand cap assemblyfor positively mounting and retaining the clip upon the cap, one end ofthe clip projecting into the interior of the cap through alongitudinally extending slot in the side wall of the cap adjacent itsclosed or outer end, and a novel means and manner of pivotally andtensionally mounting the end of the clip in said cap.

The present invention is a division of our copending application SerialNo. 356,506, filed May 21, 1953.

Further objects are to provide a construction of maximum simplicity,efficiency, economy and ease of assembly and operation, and such furtherobjects, advantages and capabilities as will later more fully appear andare inherently possessed thereby.

in the drawing:

Figure 1 is a top plan view of a cap for a writing instrument andembodying the novel clip.

Fig. 2 is a view in side elevation of the novel assembly of Fig. 1.

Fig. 3 is a view similar to Fig. 2, but broken away and showing invertical cross section the spring mounting ofthe anchored end of theclip in the closed end of the cap.

Fig. 4 is a view similar to Fig. l, but broken away and showing inhorizontal cross section the spring mounting of the clip in the cap ofthe writing instrument.

Referring more particularly to the disclosure in the drawing in which isdisclosed an illustrative embodiment of the present invention, thewriting instrument 10 is shown provided with a cap 11 adapted to bemounted on the outer end of the barrel or body 12 of a writinginstrument, such as a ball point pen, mechanical pencil, fountain penand the like having a barrel provided with a writing point.

The cap is provided with a pocket clip 13 adapted to be attached to thepocket or other part of the clothing where the writing instrument isretained when not in use. To prevent accidental or unintentional removalof 2,837,801 Patented June 10, 1958 ICC" the writing instrument from thepocket or other support or part of the clothing, the clip 13 is adaptedto yieldingly grip the material of the pocket or other support butpermit ready removal when the writing instrument is intended for use.

The clip 13 is provided with a shank 14 having at its free end a roundedtip or engaging end 15 and at its other end is provided with a shoulder16 on its pivotally mounted or fulcrumed end or enlargement 17. To mountthe pivotal or fulcrumed end 17 in the upper or outer end 18 of the cap11, the end 17 is contoured to be projected through a longitudinallyextending slot 19 in the wall of the cap shell 21 and anchored in thecap 11. This enlarged end 17 is provided with a notch or recess 22 toconformably receive an edge 23 of the cap shell 21 at the upper or outerend of the slot 19 and fulcrum about this edge as the rounded end orengaging tip 15 on the free end of the shank 14 is moved toward or awayfrom the shell 21 of the cap 11.

The upper or pivotal end 17 of the clip is provided with another notchor recess 24 disposed at the lower edge of the end 17 into whichprojects a lip 25 on a projected part or extension 26 of a clamp member27 mounted in the outer or upper end of the cap 11. A liner 28 is alsoprovided in the cap shell 21. This clamp member 27 has a substantiallycup-shaped base 29 provided with the rearwardly extending projection 26substantially conforming to the internal surface contour of the capshell 21. Thuswhen the cap, 11 is assembled with the projection orextension 26 aligned with the slot 19, the reduced end or lip 25 is bentover and anchored onto the cap shell 21 at the lower end of the slot 19as shown in Fig. 3.

Spaced approximately 180 from the projection 26, the clamp member 27 isprovided with inwardly projecting, elongated and spaced flanges 31adapted to provide a longitudinally extending channel for receiving andretaining a coil spring 32, the lower orinner end of which spring seatsagainst or abuts the base 29 and the upper or outer end of this springbears against the shoulder 16 on the pivotally mounted or fulcrumed end17 of the rigid pocket clip 13.

As will be evident from Fig. 3, when the end or lip 25 projects throughthe slot 19 in the cap and is bent onto the cap shell 21, the enlargedor fulcrumed end 17 of the clip 13 is locked in the cap 11. Then as thefree end or rounded tip 15 of the spring-loaded clip 13 is moved awayfrom or toward the cap 11, the enlarged end 17 of the clip fulcrums orpivots about the edge 23 of the cap shell 21. r

From the above description and the disclosure in the drawing, it will beapparent that the present invention comprehends a new form of clip andcap assembly for writing instruments and a novel means and manner ofspring-loading the clip and retaining it in operative position.
